Fuel in Radiator Overflow

[7.3Excursion4x4]

I just changed the injector cups, using RiffRaff's injector cup tool, when I put in the new Stage 1's. I was getting a lot of fuel in the overflow before replacing the cups the 1st time and I found 2 of the old cups had small cracks in them.

On startup after sitting for a couple hours, it smokes (White/maybe a little blue) like a farm tractor and sounds like it is missing a few injectors. After a minute or so, it runs great and doesn't smoke at all.

After dinner, I am going out to put the AE on it to see what I can find

Is there any other place or cause that would allow fuel to get into the overflow bottle? I've been seeing small amounts in the overflow since the replacement but I figured it was residual from the first cup failure. Today, I noticed the overflow was boiling over with fuel.

Before I get irate, and have to tell the wife I need to do it again, someone give me some good news and a simple fix.

It can only be the cups or a defect in the head which is unlikely. Did you use the proper permatex and let it cure good?

I did. I used the permatex from the Riffraff kit and let it cure for 24 hours. I guess I get to do it again as soon as I can get the tools back from Riffraff again.

At least the wife was not mad.

I feel your pain. You learn best when you do things twice. Been there done that a time or ten lol
